These are just a few of many Sanborn maps that became available recently via the Indiana Spatial Data Portal on IU's website (http://gis.iu.edu/). IU's November 7, 2011 press release states: "Considered a treasure trove of American history sought after by genealogists, urban planners, sociologists and a gamut of other researchers, Sanborn Fire Insurance maps, first created beginning in 1867 for assessing fire insurance liability for buildings in U.S. cities, are now available to the public for more than 300 locations in Indiana." The pre-1924 maps, now in the public domain, may be downloaded from the site with no use restrictions.
